Relationship between sleep disorders, depression, and obesity in older adults with or without sarcopenia

Introdução

During the aging process, a series of changes occur in the body, generating a greater chance of older adults developing obesity, poor sleep sarcopenia and emotional disorders, which are associated with decreased mobility an increase in a range of diseases, especially chronic ones.

Objetivo

To identify the association between sleep disorders, depression and obesity in sarcopenic and non-sarcopenic older adults.

Métodos

The study was cross-sectional, with data collection performed by the Study Group on Physical Education, Physiotherapy, Sport, Nutrition and Performance (GEFFEND/UNICESUMAR), which involves professionals from various areas whose aim was to provide an interdisciplinary approach to therapy for individuals with obesity or overweight. Individuals over 60 years old and insufficiently active were included, and they completed three sleep assessments - the Pittsburgh, Berlin and Epworth instruments. In addition, they underwent a bioelectrical impedance assessment of body composition and dynamometry to evaluate isometric manual strength; and completed the Patient Health Questionnaire-9 for depression, and the Strength, Assistance with Walking, rising from a chair, Climbing stairs and Falls (SARC-F) questionnaire to assess the possible presence of sarcopenia. For statistical analysis, the chi-square test was used to verify the association of categorical variables.

Resultados

A total of 77 older adults were recruited. Among the 77 participants, 67 were not diagnosed with sarcopenia and 10 were diagnosed with sarcopenia. The results demonstrated an association between sarcopenia and the volunteers' BMI (X2=16.21 p=0.001). However, no significant relationship was found between sarcopenia and depressive symptoms (X2=2.74 p=0.601). Regarding sleep variables, there was no association between of the Pittsburgh, Berlin and Epworth instruments and the diagnosis of sarcopenia (X2=2.02 p=0.154; X2=1.33 p=0.513; X2=0.239 p=0.625), respectively.

Conclusões

Our study findings indicated that a higher BMI was associated with sarcopenia in older adults. Although we did not obtain significant results for depression and sleep quality, both variables deserve further investigation, as our sample was small and this was a limitation of the study.
